12-24GHz Frequency Multiplier
GaAs Monolithic Microwave IC
Description
The CHX2090 is a cascadable by 2 frequency
multiplier monolithic circuit.
It is designed for a wide range of applications,
from military to commercial communication
systems. The backside of the chip is both RF
and DC grounds. This helps simplify the
assembly process.
The circuit is manufactured with a PM-HEMT
process, 0.25m gate length, via holes through
the substrate, air bridges and electron beam
gate lithography.
Main Features
Broadband performances : 11-13GHz
15dBm output power for +12dBm input power
DC bias : Vd=3.5Volt@Id=50mA
Chip size : 1.67 x 0.97 x 0.10 mm
